New Exoplanet discovered by NASA: What does this planet reveal about our solar system?

A new study published on NASA’s official website has reported detection of an exoplanet. This exoplanet is much like our Jupiter. Here is everything you need to kw about this Jupiter like planet.

Exoplanet HIP 67522 b

NASA published reports of detection of exoplanet HIP 67522 b on its official website on June 24, 2020. According to NASA, this planet appears to be youngest hot Jupiter ever found. This hot Jupiter is orbiting a well-studied star, which remains unspecified by NASA yet.

study also suggest that this hot Jupiter is only a few million years old, which means that it is much younger than or hot Jupiters, which are at least a few billion years old. Exoplanet HIP 67522 b is located only 490 light-years away from earth. Its has a diameter which is 10 times that of earth, in or words, it’s almost as big as our Jupiter. Jupiter like planet takes only seven days to orbit its star, which has almost same mass as our Sun. massive size of this planet strongly indicates, that like our Jupiter, exoplanet HIP 67522 b is also a gas giant.

How was Jupiter like planet identified?

HIP 67522 b was identified as a planet candidate by NASA's Transiting Exoplanet Survey Satellite (TESS). This techlogy detects planets via transit method. Which means that scientists search for small dips in brightness of a star, indicating that an orbiting planet has passed between observer and star.

Aaron Rizzuto is an exoplanet scientist at University of Texas at Austin who led this study. Aaron revealed to a science portal that we can learn a lot about our solar system and how it came to be, by studying se exoplanets. se exoplanets will help us to understand, how unique or common everything in our solar system is. Rizzuto claimed that exoplanet scientists are finding out how our solar system fits in bigger picture of planet formation in universe.

How do hot Jupiters get so close to ir parent stars?

Currently, re are a few hyposes about how this new planet is so close to its star.

• First is that y form re and stay put. However, it’s hard to imagine planets forming in such harsh conditions. scorching heat from star will vaporise all planet-forming material.

• Second suggests that hot Jupiters form far away from ir parent star. Even past a boundary called sw line. After ir quiet formation, y wander close to ir parent star.
• Third hyposes suggest that hot Jupiters actually move closer to ir parent's star due to gravity of or planets around star, that drive ir migration.
